The new minister's wife had a baby. The minister appealed to the congregation for a salary increase to cover the addition to the family.The congregation agreed that it was only fair, and approved it.
When the next child arrived, the minister appealed again and the congregation approved again.
Several years and five children later, the congregation was a bit upset over the increasing expense. This turned into a rather loud meeting one night with the minister. Finally, the minister stood and shouted out,"Having children is an act of God!!"
